Weird problems with the Internet on your computer? 20

Try changing the physical address of the network card.

1. The network is not connected. Now most of the home users use ADSL mode to surf the Internet, so the stability of ADSL cat determines the stability of your network, I have seen the user's cat often crashes, need to be manually restarted, in order to restore the network unblocked, in this case, hurry up to call ** to the telecommunications bureau, replace a cat, you can.

2. The NIC settings are incorrect. A lot of users don't know much about network settings. For some network-related settings, such as DNS settings, they are often filled in incorrectly, resulting in inability to access the Internet.

3. Internet Explorer error. This is also a problem that is often encountered, and now there are more rogue software on the network, and often some garbage plug-ins bring a great burden to IE, and improper user operation will cause IE to fake death. Don't worry about this situation, QQ doesn't provide a browser TT?

Try to see if you can surf the Internet, if you can, it means that IE is broken, try IE's repair software, maybe there will be a surprise.

4. The IP address of the LAN user is set incorrectly. Users who are often in the LAN have set the wrong IP address, resulting in IP address conflicts and inability to access the Internet.

How is the IP configuration of the machine that cannot access the Internet correct, then you have to check that the network card of the machine is driven correctly. You first need to make sure that your machine can connect to the local area network, and it is highly recommended that you change the network card of the machine that cannot access the Internet. Try again.

to determine if it is a problem with the network card.

Look at your network card.

Let me tell you about it, reinstall the driver of the network card, and then reset the IP, subnet mask, and gateway. Try it and see it works.

Fill in both the DNS and the alternate DNS, and I have friends in the unit This problem is because the spare DNS is filled in incorrectly, and it can be on at first, but sometimes it can't be on. I don't know why you tried it first.

Maybe the VPN has disabled the port of this machine, and sometimes it's actually a small problem.

It may be that the remote device, such as the router, has made a policy to bind the MAC address.

Try to change the MAC address of the network card.

There should be no problem.

It may also be that the dependent network service is not enabled.

This problem can occur when system files are missing.

Reinstall the NIC driver. If not. Look at your units. Has anyone pretended to be a cyber enforcement officer? It may be that this blocked your Internet access`

This happened in our unit.

Check to see if the VPN has set up restrictions on Internet access.

Yes, yes,

Press Yes and Yes Small is small.

Yes, yes, and there is a hair no.

It's your local network operator! For example, Henan Netcom has blocked the Internet ports of many switches, and you can only get on one machine, you can crack it with the next Polaris, or you can use the Internet access method that comes with Windows.

Is the network card broken, it's that simple.

Try the network card re-drive.
